tacle proper, securing greater efficiency.

vGene/ral Description..

In the accompanying drawing- Figure l is a sectional proved churn.

Figure 2, atransverse section, on an enlarged scale,A

of the receptacle thereof. Figure 3, a perspective view, on the same scale as iig. 2, of a portion of the agitator detached.

A, in g. 1, may represent a frame ot' suitable form.

B ,is a tubular box, pivoted centrally, z, in the frame A, and-forming the receptacle of the apparatus.

C is an agitator or rifle for arrangement in the receptacle B, as represented in figs. l and 2, to 'break the globules of the cream and collect the butter, being composed of a number of perforated plates, y, attached to a base, x, which is adapted to extend from end to end of the receptacle, and be secured thereat, said plates being so disposed as to extend across the receptacle, and to project half way, more o1' less, to its top.`

The receptacle B is made of about sixteen times its width ,in length, and is preferably rectangular in forni, as shown, to facilitate its construction and the application of the proposed form of agitator. Its great length relatively to its width enables this construction,

and is found further to improve the operation of the churn.

One or both of the ends or heads w w of the receptaclc B are made removable, as represented, to

give access to its interior, being secured inplace by hooks lu and studs u, or their-equivalents; both being removable, as shown, greater facility for cleaning is afforded. They may preferably be hinged.

Pins t or their equivalent, on the inner sides of the perspective view of any iin-l ends w of the receptacle, may hold the agitator G down.

enables its oscillation. A central perforation or mouth, r, in the top of the receptacle, furnishes means for introducing the cream and for the admission of air, being provided with a suitable plug or valve, if necessary.

Tile proposed dimensions of the apparatus are as follows: height of frame A, three feet; distance of handles vs apart, three feet, each being eighteen inches from the pivot z of the receptacle; receptacle, four feet by three inches, or eight feet by six inches.

Wood is preferably employed, as far as applicable, in the manufacture. The remaining parts may be made of any suitable material.

Operation.

".lhe operation of the churn is as follows:

The parts all being in position, the cream is introduced into the receptacle through the mouth r, by means of a funnel. The receptacle may be filled about half full. The operator then takes his position behind the apparatus, 'taking one of the handles s in each hand, and slowly oscillating the receptacle by pressing down and lifting, alternately, with his respective hands. As the respective ends of the'receptacle are elevated the cream is made to rush into the other, o ver and through the beaters 1, andA is thus most rapidly and effectively agitated, and the deposit ofthe butter secured.

On the operation being finished, which may be. ascertained by test, one of the ends w is removed, and the milk poured off. The agitator C is then withdrawn, bringing out the butter, which is removed from its platesin usual manner. The remaining end w may then be removed, and the in terior of thev receptacle scalded and cleansed. y

with the pivotal 'frame A, and the construction and arrangement of the said receptacle and rifle, as

herein represented and described, for'the purposes set` forth'.
